[PVFS-users] pvfs mounting problems with minimalistic kernel

[Kaveh Moallemi]

Hello, I'm having some problems with mounting pvfs .... I'm currently using 
pvfs-1.6.2 on linux-2.4.21 patched with bproc (3.2.6) on a 2 node test 
cluster.  On the server side (10.0.0.1) everything works just fine, I can 
start the mgr, iod and pvfsd programs and then mount /pvfs-meta without any 
problems.  On the client side however, I can install the pvfs.o module and 
run pvfsd but mounting fails:

1) If I try:
$mount 10.0.0.1:/pvfs-meta /mnt/pvfs -t pvfs
I get:
(inode.c, 340): pvfs_super_iget crapped out at ll_pvfs_lookup
(inode.c, 196): pvfs_read_super aborting!
mount: Mounting 10.0.0.1:/pvfs-meta on /mnt/pvfs failed: Invalid argument

2) If I try:
$mount.pvfs 10.0.0.1:/pvfs-meta /mnt/pvfs
I get:
Kernel does not support tcp: No such file or directory
mount.pvfs: server 10.0.0.1:3000 not responding, giving up

Of course I've configured the kernel with TCP support (BProc uses TCP and it 
works), so I really don't understand the error message.  I should mention 
that the client is diskless and thus uses a very minimalistic kernel.  I 
suspect that I'm missing something in the kernel configuration .... so I 
would greatly appreciate any suggestions!

By the way, I'm sure that there is nothing wrong with the server since I can 
mount pvfs from a third test machine (not diskless) on the same network.
